The Hollyoaks actress explained that the photo had been taken in a "pre-wedding photoshoot" after the happy couple had both lost weight and "were feeling proud" of themselves.
"Linc was coming out of the surf like James Bond in front of a bunch of people," she wrote. "Then a wave took him down. I laughed til I was sick but luckily the moment was captured!!"
She then left an incredibly heartfelt message for the man she called the "best husband" as she wrote: "Even with the challenges we currently face, my husband makes me laugh every day.
